Profoto just announced a brand new digital flipbook featuring information about their lights: especially with education about their D1 monolight vs speedlights. Plus you’ll learn about their Light Shaping Tools and accessories. Sure there is marketing in there, but there are also in depth explanations and tutorials on monolights vs hot shoe flashes.
There’s more than just that though, there are actually useful tips and lighting diagrams in there from portrait photographers such as David Bicho, Dixie Dixon, Tony Corbell and Andrew McGibbon.
